Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[{5}^{p}{r}^{2}{\imath }^{2}{m}^{2}{e}^{2}p\]
Use Square Rule: \({i}^{2}=-1\).
\[{5}^{p}{r}^{2}\times -1\times {m}^{2}{e}^{2}p\]
Simplify.
\[{5}^{p}{r}^{2}\times -{m}^{2}{e}^{2}p\]
Regroup terms.
\[-{e}^{2}{r}^{2}{m}^{2}p\times {5}^{p}\]
-e^2*r^2*m^2*p*5^p
